Tools (7)
| Name | Description | Schema |
|---|---|---|
get_social_media_placement | Look up one social media placement by id and return its frame size, aspect ratio, first-party safe-area insets in px, usable box, and the official page the figures came from. Pass sourceWidth and sour | typed |
list_social_media_placements | List every supported social media placement (or one platform's) with frame size, aspect ratio, safe-area insets in px, usable box and first-party source URL, plus links to the same dataset as CSV, JSO | typed |
check_safe_area | Check whether a rectangle (a caption, logo or button, in px on the placement's own frame, origin top-left) stays inside the placement's safe area, and by how many px it intrudes past each edge if not. | typed |
calculate_aspect_ratio | Reduce any pixel size to its simplest aspect ratio (1920x1080 is 16:9) and the nearest even size an H.264 encoder accepts, and, given a target ratio, solve the missing width or height and return the c | typed |
estimate_video_bitrate | Video size and bitrate arithmetic for a clip of durationSec. Pass videoKbps to get the encoded file size (MB, GB, MiB, GiB); pass targetCapMb to get the highest video bitrate that fits that file size. | typed |
convert_subtitles | Convert subtitle text between SubRip (srt) and WebVTT (vtt), optionally shifting every cue by shiftMs, and return the converted text with the detected source format, cue count, parse warnings (with li | typed |
estimate_tempo | Tempo arithmetic for editing to music: pass tap timestamps (ms) to estimate BPM with a stability and confidence rating, or pass a known bpm. Either way it returns the beat length, a delay table (strai | typed |
